Assuming he stays healthy/competitive, it would be hard to decline this deal as a 23year old, IMO......Also if he doesn't get extended and hits the market around 26-27yrs old he's going to be looking at Hamels dollars........Look at the Kershaw financial options. Considering Floyd is making 9.5M it makes it a nice deal.

8yr/58M Similar to the Strasburg deal he signed out of college.

This put him past arbitration, which he would (assuming) be awarded pretty solid salary (LHP, eats IP, K's, competitive)
